Patent attributes
A non-pneumatic tire (1) of the present invention includes an attachment body (11) attached to an axle, a ring-shaped body (13) which surrounds the attachment body (11) from the outside in a tire radial direction, and coupling members (15) which displaceably couple the attachment body (11) to the ring-shaped body (13), wherein a plurality of coupling members (15) are arranged in a tire circumferential direction and include elastic coupling plates (21 and 22) whose opposite ends are respectively coupled to the attachment body (11) and the ring-shaped body (13), and a bending rigidity EI1 of the elastic coupling plates (21 and 22) represented by E1×W1×t13/12 when the average thickness in the tire circumferential direction is t1 (mm), the average width in a tire width direction H is W1 (mm), and the Young's modulus is E1 (MPa) is smaller than the bending rigidity EI2 of the ring-shaped body (13) represented by E2×W2×t23/12 when the average thickness in the tire radial direction is t2 (mm), the average width in the tire width direction H is W2 (mm), and the Young's modulus is E2 (MPa).
